Tntdb is a c++-class-library for database access.
It implements a database-independent layer, which
loads the actual driver dynamically when a
connection is made. The classes use automatic
resource management with reference counts.
Resources are freed when the classes go out of
scope. Error handling is done with exceptions
(derived from std::exception). There are STL-like
iterators for result sets and rows, and also the
cursor is an STL-like iterator. It is written in
standard C++ with Linux. Drivers for PostgreSQL,
sqlite3, MySQL, and Oracle are available.

The Voodoo compiler is an implementation of the Voodoo programming language. The Voodoo programming language is a low-level programming language, abstracting over the platform's instruction set and calling conventions, but otherwise leaving the programmer free to do anything at all. The Voodoo compiler supports multiple target platforms and provides a stand-alone compiler, as well as a Ruby module for programmatic code generation.

foldroid is a mail folder selection tool. For people who use mutt or a similar text mode mail reader, foldroid is a convenient tool to navigate through your mail folders. It shows how many messages are in each folder and how many of them are new. This, combined with a tool like procmail to sort mail messages of mailing lists into separate folders, makes selecting the right folder to read easy. Foldroid works best when you run it in a screen session, because it then starts every instance of mutt in its own screen.

javaXUL provides a simple to use XUL implementation, including CSS and JavaScript capabilities, for use in Java projects. Some uses include the embedding of an XUL stack in a Java browser and using XUL as a UI language in Java applications, including the ability to communicate with Java. It is not intended to compete with much more complete RIA offerings such as Flash, Silverlight, or javaFX. Instead it tries to leverage the expressivity of XUL in the Java development area. Compatibility with Mozilla XUL (such as the Firefox implementation) is a goal.

MDIUtilities provides a set of utility classes that can be used for desktop application development. It contains a network preferences implementation, XML utility classes, geometry utility classes, additional Swing classes, and other miscellaneous classes.

Duda I/O is an event-driven based web services and application framework for Linux. The stack provides a friendly C API to build solutions based on HTTP or Websockets. It support third-party components such as JSON, Redis, SQLite, and others.

ntdisp, short for NtD In System Programming, is a system for programming LPC and STM32 (and possibly other) embedded devices. It provides three different frontends, a GObject-based library (for developers), a commandline utility (for computer geeks), and a GTK+3 frontend (for less geeky users).

OnPosix is a tiny library to abstract POSIX mechanisms to C++ developers. Most features offered by this library can be found either inside the Boost library or in a library compliant with the C++11 standard. Unfortunately, however, for some embedded Linux devices, these libraries cannot represent viable solutions, due to the lack of memory space (for the Boost libraries) and the lack of a new C++ compiler (e.g., on Xilinx MicroBlaze). On these platforms, the OnPosix library represents a good and cheap solution to have object-oriented POSIX mechanisms. The library offers support for threads, mutual exclusion, sockets, logging, timing, etc.
